What Is Maternal-Fetal Medicine?
Maternal-fetal medicine (MFM) is a sub-specialty within obstetrics and gynecology that provides specialty care for women with high-risk pregnancies. A high-risk pregnancy is one that involves increased health risks for the mother, fetus, or both. Conditions that can pose a risk include high blood pressure, diabetes, or having a short cervix. Someone with a high-risk pregnancy may require extra care before, during, or after birth.

Talk to your doctor about getting a referral for high-risk consultation with one of our MFM physicians.Risk Factors For A High-Risk Pregnancy
During the course of your pregnancy, a Stamford Health MFM will supplement – but not replace – the care of a primary OB-GYN. An MFM will work in collaboration with your OB-GYN and any other specialists that are needed. If you have any of the following risk factors, speak with your doctor about consulting with an MFM physician.

Other Reasons It May Be Beneficial To See An MFM During Pregnancy Include:
- Abnormalities of the fetus, placenta, uterus, or cervix.
- Multiple gestation (twins, triplets, or more).
- Pregnancy after in vitro fertilization (IVF).
- Family history of a genetic condition, disability at birth, or childhood condition.
- Concerns about baby’s growth, environmental, or medication exposures.
- Behavioral health conditions, such as anxiety, depression, bipolar disorder, or post-traumatic stress disorder.
Screening & Diagnostic Services Offered
An OB-GYN may refer you to see Stamford Health’s MFMs for further testing, including genetics evaluation or antepartum fetal testing. Your pregnancy may require additional ultrasound imaging performed by Stamford Health’s sonographers with advanced training. Additional screening and diagnostic services offered by MFMs include:-
FIRST TRIMESTER
-
SECOND TRIMESTER

THIRD TRIMESTER
GENETIC COUNSELING AND TESTING
Our genetic counselors and geneticists who specialize in prenatal and fetal genetics can conduct screening and testing to look for any high-risk issues.
NUCHAL TRANSLUCENCY ULTRASOUND
This ultrasound measures the thickness of the space at the back of the fetus’s neck. An elevated measurement indicates an increased risk for Down syndrome or other congenital anomalies.
TRANSVAGINAL ULTRASOUND
A technician or doctor will insert a probe into your vagina as a way to see your uterus, ovaries, tubes, and cervix.
GROWTH ULTRASOUND
These ultrasounds check to see how well the baby is growing. Some women may have an ultrasound during their first trimester as well.
FETAL ECHOCARDIOGRAM
This noninvasive test evaluates your baby’s heart using sound waves. It is usually performed between 20 to 24 weeks of pregnancy.
FETAL ANATOMICAL SURVEY
At around 18 to 20 weeks of your pregnancy, an ultrasound will be performed to assess the structures of your baby such as heart, kidneys, fingers and toes, and to detect any anomalies or issues with growth.
CERCLAGE PLACEMENT
In this procedure, the cervix is temporarily stitched closed during the second trimester to help hold a pregnancy in place and prevent a preterm birth.
BIOPHYSICAL PROFILE TESTING
The biophysical profile uses a scoring system to evaluate a fetus’s health based on the fetal heart rate, breathing movements, body movements, muscle tone, and amount of amniotic fluid.
FETAL NON-STRESS TESTING
Using an elastic belt with a sensor attached, your baby’s heart rate and movements will be tracked over a period of about 20 minutes.
